we have a JD 210C that we have an issue,, it defaults to N after about 5-10 mins of use ,, pressures are good and clucth botton is working fine with no disruption during operation, But here is the wierd part <<< if I shut of the ing key and restart asap it goes right back to work for about 5-10 mins and defaults to N again any suggestions guys all systems pressure are to spec and i have ran a muilt meter in the system to see if the cultch button is causing the issue also pressure are fine when this happens
Have you checked the voltage at clutch solonoid before and just after default. Don't have manual with me today, but wonder even if button is ok,, does the solnoid heat up and cause it to disengage? Or if ground disengages it, and you have a rubbing wire, maybe a short? Keep us posted
thanks for the info yes i had a meter hooked up no voltage to clutch . oil press stays at 40 to 50 psi .
Solenoids need to be powered up all the time so it will stay engaged. But if you have a break in the internal solenoid coil you will still have 12 volts to the connection but when the coil heats up for 10 minutes it will separate at the break until it cools down again to reconnect. I've seen this happen before in an ignition pickup coil. Can you switch the forward solenoid with the reverse one to see what happens?
tractor has no coils it is manual shift just has a elect clutch for shifting .thank you .
If you have a solenoid on your JD backhoe it has a coil inside. A solenoid is an electro magnet that consist of a coil of wire. When activated causes a metal part to move and in this case engages your transmission. If the coil is broken your transmission will not engage or at least not dependably.
I have down loaded the operations and tests manual, do you still need help with this?
